ERWndi magetsi-kukana welded zitsulo chitoliro, Kukaniza welded zitsulo chitoliro lagawidwa kuwombola welded zitsulo chitoliro ndi DC welded zitsulo chitoliro mu mitundu iwiri.AC kuwotcherera mogwirizana ndi mafurikwense osiyana amagawidwa otsika pafupipafupi kuwotcherera, NGATI kuwotcherera, kuwotcherera kopitilira muyeso-IF ndi high-pafupipafupi kuwotcherera.Kuwotcherera kwapafupipafupi kumagwiritsidwa ntchito kwambiri popanga chitoliro chachitsulo chochepa thupi kapena chitoliro chachitsulo cha khoma, kuwotcherera pafupipafupi kukhudzana ndi kuwotcherera ndi kulowetsa.Kuwotcherera kwa DC kumagwiritsidwa ntchito ngati chitoliro chaching'ono chachitsulo.Chifukwa chake, pankhani ya chitoliro chophatikizika, chowotcherera chokwera kwambiri chomwe chimaphatikizidwa mu chitoliro cha ERW ndi njira yowotcherera yothamanga kwambiri kuti ipange mapaipi a ERW.ERW Longitudinal zotsogola zogulitsa zogulitsa mafuta ndi gasi zosungirako ndi zoyendera, utsogoleri wabwino, chitoliro chachitsulo chochuluka.

ZOONA mapaipi achitsulondi yochepa Submerged Arc kuwotcherera Zitsulo Chitoliro, amene ndi ntchito m'madzi arc soldering ndondomeko kupanga zitsulo, ndondomeko umapanga kachulukidwe mkulu kwambiri panopa, wosanjikiza flux kuteteza kutaya mofulumira kutentha, ndipo anaikira mu kuwotcherera dera.Kulowetsedwa kwa arc weld wapamwamba kwambiri, kupanga kwapamwamba kwambiri, arc ndi kusuta makhalidwe ochepa a arc welded chitoliro chimagwiritsidwa ntchito kwambiri muzotengera zokakamiza, kupanga zitoliro, matabwa, kutsika kwamadzimadzi, ntchito zachitsulo.Zogulitsa zazikulu za mapaipi azitsulo a SAW LSAW Chitoliro chachitsulo, Chitoliro Chokhazikika Chokhazikika cha Arc Chowotcherera Chitsulo cha LSAW chitoliro chachitsulo, ndikugwiritsa ntchito kumizidwa kwa arc kuwotcherera kwa chitoliro chachitsulo chowongoka.

Kusiyana pakati pa erw ndi saw steel pipe
Monga ERW zitsulo chitoliro ndi anaona zitsulo chitoliro mu chitoliro pa kupanga, kuwotcherera ndi ndondomeko ndi osiyana, kotero kuti mitundu iwiri ya zitsulo chitoliro mu ntchito pali kusiyana.
(1) ERW chitsulo chitoliro pamwamba khalidwe ndi apamwamba kuposa ozungulira kumizidwa arc welded chitoliro, ERW zitsulo chitoliro pamwamba ndi yosalala, yosalala, wokongola, SAW zitsulo chitoliro mkati ndi kunja weld kulimbitsa.

(2) ERW zitsulo chitoliro kuwotcherera chilema mitundu ndi zochepa kuposa macheka zitsulo chitoliro.Anawona zitsulo chitoliro ndi zosungunulira waikamo, mitundu yambiri ya zolakwika, kuwonjezera voliyumu kupunduka, pali waya-mzere msampha.ERW zitsulo chitoliro kuwotcherera zilema yekha waya-mzere ndi kuwotcherera molunjika, ndi kuyendera ndondomeko yosavuta kutsatira, ndi zolakwika pazipita kusinkhasinkha pa, kamodzi kusowa kwenikweni, akupanga kunyezimira amphamvu, zosavuta kudziwa.

(3) Chitoliro chachitsulo cha ERW chokhudzana ndi chitoliro chachitsulo chotsalira chotsalira ndi chochepa.Popeza kupindika kwa chitoliro cha ERW munjira yopindika mokwanira, kuphatikizika kozungulira kozungulira kozungulira, kusinthika koyang'ana koyang'ana ndi khosi, kupangitsa kupsinjika kwa chitoliro cha ERW kumakhala kocheperako.kuyezetsa thupi anasonyeza kuti mfundo zomwezo, zinthu zomwezo ERW chitoliro pambuyo incision pa olamulira, ndi axial ndi zopingasa incisions ang'onoang'ono kusamutsidwa kuposa ozungulira mizere arc welded chitoliro.

(4) ERW Chitoliro chonse ntchito chimodzimodzi, pamene chitoliro amakhala chilema, zitsulo zidutswa chiweruzo, kulola kuwotcherera.SAW zitsulo chitoliro analola, ndi chitoliro kuwotcherera ntchito ndi ntchito wonse ndi zosagwirizana, kuwotcherera malo sachedwa kupsinjika dzimbiri akulimbana.Zoyeserera zikuwonetsa kuti kutopa kwa chiwombankhanga kuyesedwa kwa ERW chitoliro chozungulira chakumizidwa ndi arc welded chitoliro kutalika kuposa moyo.
